Rol van de hippocampus bij geheugen

The hippocampus is a small, seahorse-shaped structure in the brain that plays a crucial role in memory processing, particularly in forming and retrieving memory.

Humans have a hippocampus on each side of the cerebral hemisphere, and together, these are referred to as the hippocampi.

Rats with damaged hippocampi exhibit significant difficulties in performing tasks like recognizing objects or navigating mazes. This suggests that the hippocampus is essential for recognition and spatial memory.

Moreover, the hippocampus can physically adapt to the demands of frequent spatial navigation. For instance, taxi drivers who navigate complex city streets have been found to have larger hippocampi than the general population.

Another vital role of the hippocampus is consolidating new memories. This process involves transferring information from short-term to long-term memory storage, allowing for the creation of lasting memories.

Damage to the hippocampus, whether from injury or disease, makes encoding new memories difficult, although the ability to recall information and events before the damage remains intact.
